Crate readme

Short description Library for safe and correct Unix signal handling in Rust.

Long description Unix signals are inherently hard to handle correctly due to their global nature and the limitations set by the POSIX standard on handling functions. This library provides a global registry of actions for signal arrival, allowing multiple actions for the same signal while enabling the removal of actions. Helper actions are also provided for common use cases in safe Rust.

Features • Safe Rust implementation • Global registry of signal actions • Register multiple actions for the same signal • Chaining of previous signal handlers

Code Examples Basic usage

 use std::io::Error;
use std::sync::Arc;
use std::sync::atomic::{AtomicBool, Ordering};

fn main() -> Result<(), Error> {
    let term = Arc::new(AtomicBool::new(false));
    signal_hook::flag::register(signal_hook::consts::SIGTERM, Arc::clone(&term))?;
    while !term.load(Ordering::Relaxed) {
        // Do some time-limited stuff here
    }
    Ok(())
}
